Liquid Surface Tension Tester

The liquid surface tension tester measures the intermolecular forces on the liquid surface and calculates the tension value using the ring method or pendant drop method. It is used to detect the wettability of coatings, the adhesion of inks, and the uniformity of paper coatings. In printing, it controls dot spread, and in plastic film modification, it evaluates the effectiveness of surface treatments.
Selection
Select between rotational or static type based on the viscosity of the liquid to be tested; consider temperature range compatibility with sample storage conditions; precision must meet industry standards with an error margin of ±0.1 mN/m; opt for an automatic lifting module to handle high-frequency testing; the calibration module should support both the platinum ring method and the Wilhelmy plate method.

Surface Tensiometer Evaluates the Wetting and Spreading Properties of Resin Liquids
This article introduces how to use a surface tensiometer to evaluate the wetting and spreading performance of resin liquids. Wetting and spreading affect the adhesion and appearance of products such as coatings and adhesives, and the process can be described by Young's equation and the spreading coefficient.
Surface Tensiometer: Interpreting the Invisible Forces on Liquid Surfaces
Surface tension is the contractile force generated by the uneven forces acting on molecules at the liquid surface, influencing phenomena such as droplet formation and capillarity. Surface tension meters measure this force using techniques like the Wilhelmy plate method, the platinum ring method, or the pendant drop method. Their core components include force sensors, sample stages, and data processing systems.
Surface Tensiometer vs. Contact Angle Goniometer: Which One to Choose for Wetting Studies?
Surface tension meters primarily measure the surface tension of liquids and are suitable for analyzing the properties of liquids themselves, such as purity or the effects of additives. Contact angle meters, on the other hand, evaluate the wettability of solids by analyzing the contour of liquid droplets on solid surfaces, and are commonly used in surface treatment or coating research.
How does a surface tensiometer determine the success or failure of printing quality?
Surface tension is a critical factor affecting printing quality, as it determines the wetting and adhesion of ink on materials such as paper and plastic. Accurate measurement and control of the surface tension of relevant liquids using a surface tensiometer are prerequisites for ensuring printing quality.
